I received my D50 tonight and went over it closely, comparing it to my D70 and doing some test shots. I was only working at night under the lights in my house with some flash here and there, but the D50 seems to have comparable image quality to the D70 with lower noise and slightly better autofocus. There are a couple of minor missing features in the D50 (top LCD light, a few missing buttons that are instead accessed through menus) and it is a little smaller, but I wouldn't pay the extra for the D70 if I were doing it again.
